Huawei HiLink ("h" model names) modems just provide a CDC Ethernet interface
where we have to run DHCP to get an IP address (usually in the 192.168.8.0
range). While this may be bad design in general it's sometimes necessary to
support these modems.This adds autodetection and handling of these to wwan. Tested with Huawei E3030h-1.
